1. 11. Three-Dimensional Modelling of Bond in Reinforced Concrete Theoretical Model, Experiments and Applications

   Författare :Karin Lundgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-dimensional analysis; splitting effects; bond; finite element analysis; reinforced concrete; pull-out tests; non-linear fracture mechanics; frame corners; splicing of reinforcement; cyclic loading;

   Sammanfattning : The bond mechanism between deformed bars and concrete is known to be influenced by multiple parameters, such as the strength of the surrounding structure, the occurrence of splitting cracks in the concrete and the yielding of the reinforcement. However, when reinforced concrete structures are analysed using the finite element method, it is quite common to assume that the bond stress depends solely on the slip. LÄS MER

3. 12. Ionic Conduction and Bond Valence in Glasses

   Författare :Andreas Hall; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron; Phosphate; Borate; reverse Monte Carlo; Glass; Bond Valence; Structure; Diffraction; X-ray; Ion Conduction;

   Sammanfattning : Ion conducting glasses are highly interesting for several different applications, among them, chemical sensors, smart windows with variable optical properties and as electrolytes in batteries. The last example can take full advantage of the ease with which a thin film (... LÄS MER

4. 13. Anchorage of naturally-corroded, plain bars in Reinforced Concrete structures

   Författare :Samanta Robuschi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bond; corrosion; concrete; anchorage; plain reinforcement bars;

   Sammanfattning : Reinforced Concrete (RC) is the most common construction material in existing structures. However, RC structures are susceptible to deterioration over time, with corrosion of the reinforcing steel as most common mechanism. Corrosion reduces strength and ductility provided by the reinforcement bars and affects their interaction with the concrete. LÄS MER

5. 14. Reliable Assessments of Concrete Structures with Corroded Reinforcement: An Engineering Approach

   Författare :Mattias Blomfors; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anchorage; safety formats.; reliability; reinforced concrete structures; bond; finite element modelling;

   Sammanfattning : When in service, concrete structures are inevitably exposed to detrimental processes which, over time, can affect the structures’ ability to fulfil their structural requirements. The most common cause of deterioration of concrete structures is corrosion of the reinforcement; a problem that is expected to become more severe in future, due to climate change. LÄS MER

7. 15. Structural Behaviour of Deteriorated Concrete Structures

   Författare :Kamyab Zandi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FE analysis; concrete; stirrup; corrosion; bond; pull-out test; frost;

   Sammanfattning : A growing concern for better assessment of existing concrete structures has revealed a need for improved understanding of the structural effects of deterioration. The two most common causes of deterioration in concrete structures are freezing of the concrete and corrosion of the reinforcement. LÄS MER
